Garage doors appear to be simple machines that simply raise and lower a door to create an opening to the garage. Those who repair garage doors know that the mechanisms within the door and motor are more complicated than they appear. There are plenty of things that can go wrong, and also plenty of ways to fix them.
The expert in the video embedded on this page explains how garage door springs function and why they are necessary for the correct operation of the door. These springs are rated for a specific amount of uses, otherwise known as cycles. These springs can be rated anywhere from 5,000 to 30,000 cycles to give the homeowner and contractor a bit more information on what to expect from the springs.
Just like in any machine, the springs are not the only thing that helps the garage door operate effectively. There are bearing plates that can get stuck and cause the spring to also become stuck and work harder, effectively reducing the life expectancy of the spring. This is also the case with rollers on the rails that can cause early wear if they stick.
If you notice any of these occurrences in your garage door, the expert recommends you not worry, but instead have a company that can repair garage doors inspect everything, and recommend preventative maintenance so things do not fail in the future.
